> Gomry Cloud documentation: quickstart, authentication, error codes, rate limits and billing, plus a reference for every API.

Source: https://cloud.gomry.com/docs

Start with the quickstart. The rest is what is true of every API: how keys and scopes work, what each error code means, how requests are limited, and how you are billed.

## Guides

- [Quickstart](https://cloud.gomry.com/docs/quickstart) — Create a project, enable an API, mint a key and make your first billable Gomry Cloud request in about two minutes.
- [Authentication](https://cloud.gomry.com/docs/authentication) — How Gomry Cloud API keys work: the gck_live_ format, scopes per operation, and the two independent checks every request passes.
- [Errors](https://cloud.gomry.com/docs/errors) — Every error code the Gomry Cloud API returns, what causes it, whether it is retryable, and whether the failed request was billed.
- [Rate limits](https://cloud.gomry.com/docs/rate-limits) — Gomry Cloud rate limits per API key, not per IP: the default budget, the headers to read, and how to back off correctly.
- [Versioning and deprecation](https://cloud.gomry.com/docs/versioning) — How Gomry Cloud versions its API, what counts as a breaking change, and the notice and headers you get before anything is withdrawn.
- [Billing](https://cloud.gomry.com/docs/billing) — How Gomry Cloud bills: postpaid per-unit metering, one monthly invoice, per-project budget caps, and why there is no free tier.

## API reference

- [Scrape](https://cloud.gomry.com/services/scrape) — Fetch a page and extract structured data from it against a JSON schema. `POST /v1/scrape`.
- [ToolsAPI](https://cloud.gomry.com/services/toolsapi) — Find a tool that can do a task and run it — 1,700+ across 55+ vendors, on your Gomry key. `POST /v1/toolsapi/run`.
- [Superagent](https://cloud.gomry.com/services/tasks) — Give it a research question and a JSON schema. It plans, searches, reads, notices what is missing, searches again — and cites every field. `POST /v1/superagent`.

Every page linked here is also available as Markdown: append `.md` to its URL, or send `Accept: text/markdown`. The whole corpus in one fetch is at [/llms-full.txt](https://cloud.gomry.com/llms-full.txt).
